I prefer the east side one - was just there last night - but just marginally so and the room on the UWS is much pretty, despite the UES renovation. Can't tell you why though, I'm afraid - we went to the UWS awhile ago, and that's just the impression I remember coming away with. I think part of it was that the UWS seemed more expensive, but now that they've raised the wine/sake prices on the UES, it may come out to be the same.

A few years ago (?) I remember the east side being better. On the West Side one, they wouldn't bring the Gari sushi piece by piece, just all at once. Maybe it was just that night. The West side space is very nice. And the one in the theatre district too.
